I did almost this exact same install in my 2013 Edge limited except I used an Axxess DSP FD-2 10 channel DSP to keep the factory radio. I'm also running a ported 12'' with the SFB 1000d. I have a question though about the sundown amp. There are 2 pairs of speaker outs (4 total). It looks like you ran a positive from one channel and a negative from the other aka. Bridging? I just wanted to know if this was the best way to run that amp, or if i should only connect + and - to one channel and leave channel 2 empty. The speaker is wired to 1ohm.
